Key features of the Shield AVR800LCD 800VA UPS
🔹 1. Line-Interactive Technology
This UPS uses line-interactive topology, which means it automatically corrects minor voltage fluctuations without switching to battery power, helping to extend battery life while keeping your equipment protected.
🔹 2. Automatic Voltage Regulation (AVR)
The built-in AVR stabilizes low (brownouts) and high voltages without using the battery. This ensures your devices receive consistent and safe voltage levels even when mains power is unstable.
🔹 3. 800VA / 480W Power Capacity
With a capacity of 800VA (480 watts), the UPS is suitable for powering a desktop computer, monitor, router, CCTV DVR, or small office electronics during short outages.
🔹 4. LCD Display Panel
The clear LCD screen provides real-time information such as input voltage, output voltage, battery status, and load level, allowing users to easily monitor system performance.
🔹 5. Fast Transfer Time (2–6ms)
When power fails, the UPS switches to battery mode within milliseconds, preventing system crashes or interruptions for connected devices.
🔹 6. Sealed Lead-Acid Battery
It contains a maintenance-free 12V battery that provides backup power long enough to save work and safely shut down equipment during a blackout.
🔹 7. Surge and Spike Protection
The UPS protects connected equipment from sudden voltage spikes, lightning surges, and electrical disturbances that could cause hardware damage.
🔹 8. Overload Protection
If the connected load exceeds the UPS capacity, it automatically triggers protection to prevent overheating or damage to both the UPS and connected devices.
🔹 9. Automatic Restart & Recharging
Once mains power is restored, the UPS automatically recharges its battery and can restart connected equipment, ensuring minimal downtime.
🔹 10. USB Communication Port
The USB interface allows connection to a computer for monitoring software, enabling safe automatic shutdown and system management.
The applications of the Shield AVR800LCD 800VA UPS
🔹 1. Desktop Computer Backup
It provides temporary power to desktop PCs during outages, allowing users to save their work and shut down properly to prevent data loss or hardware damage.
🔹 2. Router and Modem Protection
The UPS keeps internet routers and modems running during blackouts, ensuring continuous internet access for communication, remote work, or online learning.
🔹 3. CCTV and DVR Systems
It supports CCTV cameras and DVR/NVR systems, preventing recording interruptions and maintaining security surveillance during power failures.
🔹 4. Small Office Equipment
Ideal for powering printers, POS systems, telephones, and other small office electronics to reduce business interruptions caused by unstable power.
🔹 5. Home Entertainment Systems
It can protect TVs, decoders, and home theater systems from sudden shutdowns and voltage spikes that may damage sensitive components.
🔹 6. Retail POS Systems
Shops and supermarkets can use it to keep point-of-sale systems running long enough to complete transactions during short outages.
🔹 7. Study & E-Learning Setup
Students and remote workers can rely on it to maintain power for laptops, Wi-Fi devices, and small study equipment during unexpected blackouts.
